5.0 out of 5 stars I keep on of these on hand for my furnace
Reviewed in the United States on March 26, 2023
Verified Purchase
Not sure why, but these seem to die annually on my furnace. It is an easy replacement, and the part is cheap enough. So I just keep one or two on hand for when I wake up and there is no heat flowing.

Build quality and all on these are good. I suspect it is more of an issue w my furnace.

4.0 out of 5 stars Direct Replacement for my original Coleman Furnace Fan Relay
Reviewed in the United States on January 16, 2019
Verified Purchase
Original (2002) Coleman furnace fan relay was making a loud 'snap' when fan came on. Removed all power to furnace at Breaker Panel and turned off all switches (breaker on furnace as well) and verified there was no power with AC voltmeter. While removing the OLD relay, it broke and fell apart...I guess it was time. Anyway, put this new one in and fan works without the relay 'snap' it had before. The heater element contactor/relays still bang but I am working on a solid state relay replacement for those. I judge the quality of this part as excellent (I am retired electronics/IT) and the price with shipping to be a bargain. Why the four stars? Give'm five and they'll raise the price.

Not tested yet. Could saved me a call to repair guys. If you own a heat pump you should have on hand one of each relays and condensers. Because during a heat or cold snap the repair men are very busy. The way to test them is printed on them.
